Quelle est la batterie lithium-ion la plus puissante?

En supposant que vous vouliez dire la force physique, la force physique d'une cellule Li-ion provient de son emballage. Le matériau actif sur l'électrode (Li-oxyde et autres matériaux partenaires) sont en très petites tailles de particules, et est appliqué sur une fine feuille de métal sous forme de pâte avec un liant. Une fois séché, ce matériau n'a pas beaucoup de capacités mécaniques par lui-même.

In a cylindrical cell, many layers of the metal foils with active material coating are tightly wound into a rigid cylinder. Then a metal casing is over-wrapped with metal end-caps crimped tightly together. All these various metal components contribute to the mechanical strengths of a cell. See illustration below:

The pouch cell or Li-Poly is simply the active materials on metal foils sandwiched together like a booklet sealed inside a polymer film laminated with aluminum foil. See generic illustration below:

The 3rd kind of cell design is called a prismatic cell. The active cell material is rolled up in a flat shape and placed in a metal can as show below. This provides much better mechanical strengths and protection as compared to pouch cells. It is also much easier to assemble into a larger pack and for maintenance.

If you meant which Li-ion chemistry has the highest specific-energy, then it is the NCA at this time; 254 Wh/kg. The LFP is only around 120–140 Wh/kg.

If you meant which Li-ion chemistry has the highest cell voltage, then it is the LCO chemistry; 3.7V/cell. The LFP is only around 3.2V/cell.

If you meant strength to be something else, then please clarify further.
